To all whom it may concern):y

Be it knownthat l, ROBERT a citizen of the United States, residing` latTulsa, in the county of Tulsa and State" of Oklahoma, have inventedcertain new and useful Improvements in Heating Apparatus,

of which the following is a specification.

This invention relatestoheating apparatus" and has for an object theproduction of a machine which will render the-adhesive constituent of anelastic canvas, used for insoles of shoes, etc., soluble .topermitexpeditious application of the canvas to the insole.

It is desirable inl this art to.-` apply canvas. stripsl to insoles ofshoes, etc., for reinforcing. insoles, thereby reducing possibility ofthe shoe upper becoming disengaged. With this end Vin view I havedesignedthe presentinv vention toexpedite the present methodsfof heatingthe canvas and to insure thorough heating of the same, thereby causinguniform adhesion of the canvas to the insole.

The above and other objects of this invention will be inpart describedand in part understood from the following-description ofthe presentpreferredy embodiment yof the linvention taken in connection withtheac-I companying drawings, wherein:-

Fig. 1, is a side elevational viewof a device constructed in accordancewith my invention. .4

Fig. 2, is a horizontal sectional view taken on the line 2 2 of Fig. 1,and lookingin the direction of the arrow.

Fig. 3, is a verticalsectional view of the device showing parts thereofbroken away and showing to advantage the manner of introducing steaminto the heating casings.

Fig. 4, is a fragmentary longitudinal sectional view of the casings, and

Fig. 5, is a fragmentary sectional view taken on the line 5-5 of Fig. 4and looking in the direction of the arrow.

The device of my invention consists of a supporting structure generallydesignated 6, which is formed from a plurality of vertical legs, theupper ends of which are secured in pockets 7 carried by a heating casinghereinafter described. Bracing struts 8 are provided, one of whichengages a diagonally arranged pocket 9, while the opposite end extendsinto and is pivotally engaged with one of the vertical legs. The otherstrut meinber has one end pivotally engaged with the first said strutmember and the opposite end pivotally engaged with the other supportingv f `leg on the side upon which saidxstiuts are'.` PORTER WISE,

taaie-i mounted. v, lt isto be understood that the p supportingstructure is `thesame-on-b'oth sides of this `device,:consequently onlylone side has been above described.v u f 4 Upper and lowerheatingcasings 10and` 1i respectively are,provided,;both ofwhich consists oftubularfsteam receiving members.

AThe lower casing lleisA preferably of an oblong conguration andlconsists of an rinner metallic housing 12,:whichvis encased on= its rbottom face and both' sideswith afshee't of asbestos 13 or othersuitable insulating-malt`erial.- An outer shell 14 isv4 mounted over theasbestos sheet' and has its `upper' face contiguous with they Aiiqepe'r`face of the inner'.

housing 12.' Asl-shown to advantagewint Fig. l, one endgof said-lower."c'asingzl is `bent downwardly as indicated at15. Said downwardlyc'urved end is engaged bythe rear legs of -ma'de of metal. The upper.casing also` consists ofaninner housing, as indicatedat v16,

whichlextends betweenthe top facesfand sides of said inner .housingand'outer shell.

yThe upper casing terminatesshort of the opposite endsof the lowercasing andisf'spaced therefrom byl incansof `lo-ngitu dinal'ly'ex-.f

. tending'ribs'19. :It will be observed that the ribs v19 extend. theentire length of the lower casing andaresecured Ito th'el'upper facefofthe' latter, .therebyV providing runways for a purpose hereinafterdescribed.

A steam pipe 2O extends upwardly along Vone side of the casings 10 and11 and is equipped with lateral tributaries 21, which have formedtherein perforations so that the steam may be emitted in jets in thecas-` ings. A' valve 22 is mounted inthe pipe 2O for controlling theinflux of steam into said tributaries.

taries, so that steam may be permitted to flow into the lower casingonly ifdesired. On the other hand, when it is de sired to permit thesteamto pass into yboth casings, both the valves 22 and 23 'will beopened." An exhaust pipe 24 is provided which is connected with the rearend of the upper casing 10 and communicates with the A secondvalve 23 isprovidedy .which is arranged between the two tribuioo Y latter. rlheexhaust steam can be conducted independently from the lower casing 11,if desired, or may be conducted simultaneously from both casings in viewot valves 26, used in an obvious manner.

A supporting structure for carrying canvas rolls is mounted on the rearlegs of the device and consists of supporting brackets 27, which havemounted therein a roller 28. This roller carries va plurality of rollsof canvas 29, the number of canvas rolls conforming to the number ofrunways pro vided on the lower casing. In the present instance, fourrunways have been provided, consequently, four rolls of canvas areshown. It is to be understood, however, that if desired, only one rollof canvas may be used, and on the other hand, a greater number than fourmay be used, without departing 'from the scope of the invention.

In use of'this device, the 'tree ends of the canvas rolls are mounteduponthe runways provided between the ribs 19 and are operated over saidrunways in any desired manner. Steam is introduced into either or bothof the upper and lower casings by proper manipulation of the valves 22and 23. In

assing between these casings the canvas will be thoroughly heated, so asto render the adhesive constituent of elastic canvas, tacky. The insolesare engaged with the canvas at the outlet end of the lower cassecuringthe cover 16 thereto, these bolts also servingto clamp the asbestos andhold it from displacement.

lt is to be understood that the arrangement ot supporting` structure,manner of connection of the same to the casings, form of steam valves,etc., may be changed it desired, in

conformity with the conditions under which the device of my inventionwill operate. T he structure herein shown is merely illustrative of theprinciple of my invention and I rdo not wish to be limited thereby.

What is claimed is:

it. heatingapparatus including superposed heating casings the ends ofone` of which tall short oi the ends oi the other, ribs arranged betweensaid casings and extending the full length o't the longer casing toprovide independent channels, a support tor canvas rolls supportedadjacent said longer casing` to feed a length of canvas in each channel,steam inlet pipes each of which is equipped with a lateral perf'orateextension, said extensions projecting into the casings and extending,`transversely thereacross to emit the steam in jets.

in testimony whereof l aiiix my signature in presence oi' two witnesses.

ROBERT PDRTER l/VlSE.
